Is connecting to the Internet via a US Cellular hotspot device with a Linux Mint 18.3 OS
detected and setup automatically when the OS installation is performed on the computer or
is there some type of manual configuration that needs to be done ? Or is configuration
of Internet connectivity via hotspot basically the same as a WIFI connection ?

If I install Mint from a live Mint USB ISO should I do this via my DSL internet connection
and then do whatever needs to be done to get the computers' Internet connectivity switched over
to the US Cellular hotspot AFTERWARDS ?

I have DSL, the actual user of this computer only has the hotspot, no DSL.
